T0 all whom t may concern.'

Be it known that I, MARTIN J. RooNEr, a citizen of the United States, residln at Butte, in the county of Silverbow and tate,

of Montana, have invented certain new and useful Improvements in Exercising Lens-V Shades; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention generically pertains to attachments for spectacles or eye glasses, but. more particularly to that class of the latterwhich serve as shielding mediums for the same.

One object of my invention resides 1n providing a simple and efficient shleld that may be readily and quickly attached to a spectacle lens or to the rim of a spectacle frame s o as to eli'ectually obstruct the'vls'ion through the lens, before which it 1s dis7 posed.

A further object resides in providinga unique and sim lev means for maintaining the shield in a. xed position upon the lens and in a plano parallel thereto.V

A still further object isto provide a convenient gri ping member y` means of which the sliield can be easily disengaged and removed from its position upon the lens.

Another object of my invention is to ro,- vide a shield that is inexpensive to pro uce and which may be conveniently carried upon the person for immediate `use Whenever desired.

With these and other objects in view, my invention consists of certain novel details of construction, arrangement and combina* tion of parts to be more particularly set forth and claimed.

In the accompanying drawings in which corresponding parts are indicated by similar reference characters Figure 1 is a rear elevation of my improved shield illustrating the latter as applied .to a standard size dl spectacle lens; Fig. 2 1s a transverse vertlcal section thereof taken on the line 2 2 of Fig. 1; Fig. 3 is a transverse longitudinal section thereof taken on the line 3-.-3 of Fig. 2; Fig. 4 is a rear elevation of the modied form of my improved shield, and

illustrating the latter as applied to a standard spectacle lens; Fig. 5 is a transverse vertical section thereof taken on the line of Fig. 4, andy Fig. 6 is a transverse vertical section of a modified form for my improved eye shield and illustrating the latter as applied to a standard spectacle lens.

Itis a fact well known by Opticians that with many people the retina of one eye is more sensitive and active than that of the other, the result being that the vision of one eye 1s superior to that of the other, which causes a strain on the eye having the weaker I retina that will in time lead to a serious impairment of this weaker optic. To overcome this deficiency, attempts have been made by bandaging the stronger eye to exercise and place the strain upon the weaker one, but the bandages have proved to bea constant source of annoyance, and in eve Way, are unsatisfactory. It is to this end that I provide a shield 1 cal configuration so as to approximately conform to the shape of the standard lens 2 carried b the frame 3. This shield may be compose of bone, rubber, cardboard, orally having an elliptisuitable light-obstructing material, but it-is preferably formed of rubber or Celluloid so that it will be extremely light and not annoying when disposed upon the lens vof the spectacle. The shield 1 is formed with an inwardly projecting fiange 4 disposed contiguous to'its up er end and extending from one extremity o its longitudinal axis to the other extremity thereof, for a purpose hereafter to be described. Also disposed upon they upper edge of the shield 1 at a point approximately central of its longitudinal axis is an integrally formed gripping member 5.

To enable the shield 1 to be properly disposed in front of a lens, I provide a holder 6 which is formed of the same material as the shield and has substantially the same conformation, but is a trifie smaller so that when in place contiguous to the shield 1 its lower edge will be offset from thatv of the latter. The holder 6 also has an inwardly projecting Hange 7 disposed contiguous to its upper edge and extending from one eX- tremity of its longitudinal Vaxis to the other. From this construction, it will become apparent that when the edge of the'iiange 7 on the holder 6 is placed against the edge of the flange 4: on the shield 1, said holder. will be disposed in offset relation with re-.I

1o which substantially conforms to the width of the lens and consequently greatly facili-f tates the engagement and disengagement of the shield with said lens, and also provides i' against the accidental"displacement of the shield as will be readil understood without further description. gf course, it is to be understood that the shield and holder are retained in position by means of a suitable v binder disposed glue or the like. Furthermore, the holder 6 has an extension 7 integrally formed therewith upon itsl upper edge approximately central of its longitudinal axis which when f5 the holder and shield are placed together coincides with the gripping member 5 on the shield and the two-forma handle by means of which the shield m-ay be engaged and disen aged from thel lens as will be readily understoodwithout further descrip- 3o tion. A-Thus itfwill be seen that when it is 'desired to obstruct the' vision through one lens, the shield 1 is placed above the upper edge of the lens and is then brought down- "7 wardly so' that said lens will project in the pocket 8 and be entirely enveloped by the members forming said shield, as clearly shown in Fig. 2.

As a modification of my original idea,

VJ shield 1 in' place of 'the holder 6 may be 40 'rovided' with two openings 9 which receive the ends of the wire holder 10 disposed in oiset relationto-the rear of the shield l, so

' as to form a seat for the lens, as clearly shown in Fig. 4. i,

Thus it will be seen that I have by the foregoing structure provided a shield which if properly utilized in the manner specified be ore the stronger optic will greatly augf7- ment the activity and sensitiveness of the weakerone and consequently make it possible to secure such lenses as will rovide equal vision for the eyes which be ore the unduly straining the weaker optic, as will be readily understood.

y Although in the foregoing description, l have .described certain elements as best adapted to perform the function ascribed to them, nevertheless, it lis to be understood that various minor changes as to form, substance, etc., may be resorted to within the scope of the appended claims without departing from or sacrificing any of the prinoiples of this invention. If found desirable may, instead of 'forinbetween the tv@ such as `shape and size to a standard spectacle lens,

Awardly projecting extension disposed upon use 'of this shield was impossible .without risdeae' ing the shield and holder in two pieces as hereinbefore described, construct the same integrally, that is a blank 1 a suitable thickness and having a configuration correspond- .ing to a standard lens, is channeled longitdi'nally as at 2 to form a seat for the lens das clearly shown lin Fig-6, the channel 2 forming a shield 3 and holder 4 which latter rhas its lower edge cut away and spaced from the' lower edge of the shield 3. The 75 vhand gripping member 5 disposed upon the y the upper edge of said member, a holder, an

inwardly projecting flange on the latter whose edge is adapted to abut that of the first mentioned flange whereby to dispose said holder in oiiset relation with respect to said shielding member and form a pocket to lreceive an eye glass lens, and a pair of coacting extensions formed on the upper edge of said shield and holder respectively whereby to form a handle for-the same.

' 29A lens shield comprising a shielding member 'corresponding approximately in an inwardly projecting flange formed on the upper edge of said member and extending from one extremity of its longitudinal axis to the other, an integrally formed upthe upper edge of said shielding member, a holder having configuration corresponding to that of said shielding member, a fiange formed around the upper edge of said holder, the outer edges of said flanges being adapted to` abut, whereby to dispose said holder in offset relation with respect to said shield,

i means for uniting the abutting edges of said iianges, and an extension formed on the upper edge of said holder and adapted to coincide with the extension on said shielding member whereby to coact with said extenl sion, wherebyto form a handle.

3. A lens shield of the character described comprising a translucent shielding member having a configuration corresponding to that of a standard eye-glass lens, an inteally formed hand grip risingfvertically rom the upper edge of said member at a point thereon coincident with the vertical axis of the latter, a holder having its'upper extremity secured to the central portion of theupper edge of said member and depending' therefrom in oiset relation to said meml ber forcoperation with the latter to pro- 130 meme lduce a. seat for the reception? of said lens, my hand in presence of two subscribing Witsaid holder having its lower edge adjacent messes. that of said member whereby said seat will have a depth corresponding substantially to MARTIN J' ROONEY ,E the Width of said lens substantially as and Witnesses:
